Speaking in the most general terms, you will be expected to quantitate both cation and anion. You'll want a number for both, and to be able to report how pure each is. The standards to which you have to conform: how much accuracy, how much precision, how fast an analysis, how you will multiplex samples, how you will identify and report impurity traces -- all that is up to you.
You can't exclude the possibility that any assay won't be suitable, so you're going to have to try to find out what's use for samples similar to yours.
